COTTON-GIN.

SPECIFICATION formingpart of Letters Patent No. 239,715, dated April 5,1881. Application filed March 2, 1881. (No model.)

To all whom it may concern:

Be it known that I. ISRAEL F. Bnowma citizen of the United States,residing at New London, in the county of New London and State ofConnecticut, have invented certain new and useful Improvements inGOt-tOH-GIDS and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters orfigures of reference marked thereon, which form a part of thisspecification.

This invention relates to certain improvementsin cotton-gins, and isespecially designed to thoroughly gin and atthe same time remove allinotes and foreign substances from the cotton, all of which will behereinafter more fully described, and particularly pointed out in theclaims.

Figure l is a side view, partly in section, and Fig. 2 a detached view,of the moting-shafr and saws. p

In the accompanying drawings similar letters of reference indicate likeparts of the invention.

The letters A and B represent respectively a gin-saw and stripping-brushof ordinary construction.

C is a shaft provided with a suitable number of beating-saws, C,separated by the collars D, Said shaft C is mounted in a line parallelwith the strippingbrush B, and at such a distance fromit that the teethof the beating-saws C will strike the cotton as it passes on thestripping-brush. The teeth of the [noting-saws C are preferably of theequilateral sh ape, as shown in, Fig. 1. V

The operation of the invention is as follows: The cotton, after it isstripped from the ginsaw A, comes in contact with the saws C, where itis Whipped or beaten up, thus loosening and expelling the motes andimpurities contained in it, thereby ginning the cotton more perfectlyand delivering it in an approximately pure state, ready for the cardingmachinery.

I am aware that it is not broadly new to remove the motes from cottonduring the process of ginning, and therefore I claim it; but

WhatIdo claim as new and useful, and desire to secure by Letters Patentof the United States, is-

1. In a cotton-gin, the ginning-saws A and stripping-brush B, incombination with the saws C, substantially as and for the purpose setforth.- V

2. In a cotton gin, a series of solid saws, C, adapted to remove themotes from the ginned cotton, substantially as and for the purpose setforth.

In testimony whereof I affix my signature in presence of two witnesses.
